<p>The drive comprises a driving spindle (1), two roller bearings (2) and a driven casing (3). The roller bearings (2) used as intermediaries between the spindle (1) and the casing (3) comprise each a rolling ring (5) arranged in the thread (4) of the spindle (1) and are excentrically arranged. The medial axes (6) of the roller bearings (2) are skewed with respect to the axis (7) of the spindle (1). Two sleeves (13) supported inside the casing (3) have each a reception housing (8) for the roller bearings. In order to decrease the friction loss and thereby enhance the efficiency of the driving mechanism, the reception housing (8) extends throughout 180o at the maximum so that the roller bearings (2) may be inserted perpendicularly to their axes (6) in the housings (8). </p> |
